USB: 3.5Ω Typical On Resistance
The FSA203 is a multimedia device that includes a
Double-Pole, Double Throw (DPDT) USB / audio
multiplexer, a video/microphone switch, and a video
amplifier / filter path. The DPDT path combines a lowdistortion audio and a USB2.0 switch path.
ƒ
Packaged in Pb-free 20-Lead DQFN and
2.5 x 4.5mm 20-Pin TSSOP
Video/Mic: 3Ω Typical On Resistance
Audio: 3.5Ω Typical On Resistance
USB: -3db Bandwidth at 0pF > 745MHz
This configuration enables audio and USB data to share
a common connector port. The architecture is designed
such that audio signals are allowed to swing below
ground, enabling the use of a common USB and
headphone connector for personal media players and
similar portable peripheral devices.
Video: -3db Bandwidth > 615MHz
Video: 1.0db Flatness > 6MHz
Low-Power Shutdown Mode: 1µA Maximum
Power-Off Protection on Common D+/R, D-/L,
Video/Microphone Ports
The FSA203 includes a power-off feature to minimize
current consumption when Vav or Vbus is not present.
This power-off circuitry is available for the common
D+/R, D-/L ports only.
Applications
ƒ
ƒ
Cell Phone, PDA, Digital Camera, and Notebook
LCD Monitor, TV, and Set-Top Box
Typical applications involve switching in portables and
consumer applications, such as cell phones, digital
cameras, and notebooks with hubs or controllers.
